SPECIFICATION forming part of Letters Patent No. 678,247, dated July 9,1901.

Application filed september 29, 1900. Serial No. 31,547. (No model.) I

To all whom it may concern.-

Be it known that I, ALPHONSO K. HARPER, a citizen of the United States,residing at Fairfield, in the county of Jefferson and State of Iowa,have invented certain new and useful Improvements in Combination-Tools;and I do hereby declare the following to be a full, clear, and exactdescription'of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

My invention relates to combination-tools.

In the accompanying drawings, forming a part of this specification,Figure 1 is a side elevation showing the combination-tool clamping abrush. Fig. 2 is a side elevation of the combination-tool adjusted fordriving or pulling tacks or stretching carpets, the brush being removed.Fig. 3 is a bottom plan View. Fig. 4 is a detail View showing a bottomplan of the casting E with the plate G removed.

Referring more particularly to the drawings, A denotes the handle,having a threaded casting B riveted thereto.

0 denotes a nut or screw-ring having an internal thread adapted toregister with the thread on casting B and provided on opposite sideswith ears 0, which are perforated to receive the bent ends of a wireclamp D.

E denotes a casting having a boss or hub E midway of its length,which'is perforated to receive the shank of a conical-headed bolt F,which shank is rigidly secured to the end of the handle A. The head ofthe bolt is countersunk in the boss E and is adapted to turn freely inits seat.

E denotes a claw forming part of casting E and projects upward andrearwardly from boss E at an angle of about forty-five degrees. Uponeach side of said hub project perforated lugs e e, as shown in Fig. 4.

G denotes a metal plate having a channel or slot 9 arranged centrallythereof, open at its forward end and provided upon opposite sides withperforations which register with perforations in the lugs e e. g gdenoterivets fastening the plate G to said lugs.

The casting E has longitudinal openings upon each side of its boss,through which pass the arms of the wire yoke.

E denotes teeth formed on the rear side of the casting E and extend fromend to end thereof.

To clamp a brush, the yoke is placed on the front side of thebrush-head'and the claw on the rear side, as shown in Fig. 1. The handleis turned to the right, which causes the screw-ring carrying the yoke todraw it upward in the direction of the casting E, clamping the frontside of the brush, while the claw takes hold of the rear side. Toarrange the combination-tool as a carpet-stretcher and tack driver andpuller, the handle is turned to the right until the screw-ring reachesthe uppermost screw-thread on the casting B. The parts are then in theposition shown in Fig. 2, the rear side of the casting having its teethprojecting, so that when the position of the handle is reversed, asshown in Fig. 2, the teeth will project sufficiently to engage thecarpet.

The position of the combination-tool and relation of the parts justdescribed are the same when the device is used as a tack driver orpuller. The shank of the tack is placed in the slot, the head beingplaced between the edges of the slot and the under side of the boss. Thetack is driven'in by pressing down on the handle andsimultaneouslyrocking or raising the handle to the vertical position. Todraw a tack, the head is placed inthe slot and the operation reversed.It is evident by this arrangement of parts the carpet can be stretchedand tacked simultaneously, as follows: A tack is first placed in theslot, the carpet caught in the teeth, stretched, the handle pressed downand forward, and as the teeth are released from the carpet the tacktakes hold, retaining the carpet in the stretched position.

Having shown and described my invention, what I claim, and desire tosecure by Letters Patent, is

A tool of the class described comprising a casting to receive a handle,a casting journaled to the lower end of said handle-casting and providedwith a series of teeth and a plate slotted to receive a tack secured tothe under side of said last-named casting forward of said teeth andimmediately under the handle, whereby the tack may be driven by rockingthe handle forward.

In testimony whereof I affix my signature in presence of two witnesses.

ALPHONSO K. HARPER.
